COTTON-ABSORPTIO'N-ROLL-WINDING SPINDLE.

Application filed February 5, 1925.

T all whom it may concern:

Be it known that I, GEORGE E. VVnrerrr, a citizen of the United States, residing at Vichita, in the county of Sedgwick and 5 State of Kansas, have invented a certain new and useful Improvement in Cotton-Absorp- Ytion-Roll-VVinding Spindles; and I do here by declare that the following is a full, clear, concise, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention is a tool or fixture that is put in the chuck of the hand-piece of a dental. engine, which when revolved, will wind a thin layer of absorption cotton into a roll of any size and density required. In dental operation, the excessive flow of saliva hinders the operation, and in order to keep saliva from entering cavities that are drilled into the teeth in preparation for filling, packs are placed around the teeth operated on, and these being made of an absorbent material, absorb the saliva and keep the region of operation dry. When these become full of saliva they are replaced by new packs. These packs are generally made of absorption cotton in the shape of acylindri' cal roll. A dentist requires a large amount of these cotton absorbent rolls of different sizes and densities, and in order that he should be able to make, in his spare time for future use, these rolls in quantities, I have designed a tool that he can place in the chuck of his dental engine, the same as he places a drill or grinding tool. This invention consists of certain novel parts and combination of parts, all of which will be specifically described hereinafter, reference being had to the accompanying drawings in which Fig. 1 is an elevation of the spindle in place in the chuck of the hand-piece of the dental engine, and shows the outline of the roll dotted in position.

Fig. 2 is an elevation of the spindle.

Serial No. 7,130.

Fig. 3 is a section on the line 3-3.

Fig. l is a section similar to Fig. 3 showing another type of spindle.

The spindle is composed of a shaft or light rod 1 which has a disk 3 fastened to the shank part of 4- of the shaft 1. At the junction of the disc 3 and shaft 1 is fastened the needle 2, which is parallel and adjacent to the shaft 1. The shank 4 of the shaft 1 is fastened in the chuck of the hand-piece 5 of the dental engine and when the thin layer of cotton is moved in contact of the shaft 1 the needle 2 grabs hold of the cotton and winds it around the shaft 1, and the operator using the thumb and fingers of the free hand, smooths down the roll to the required size and density, and removes.

Figures 1, 2, and 3 show only one needle 2, and that is all that is required to wind the roll. However, using a multiple number of needles does not depart from the spirit of the invention, as is shown in Fig. 4. where four needles 2, 2 2 and 2 are attached to the disc 3, parallel and adjacent to the shaft 1.

What I claim and desire to secure by Let ters Patent are 1 1. In combination with the chuck of a dental engine, a shaft, a shank of said shaft fitting-in said chuck, a disc fastened to said shank, clear of said chuck, a needle fastened to said disc and extending outward from and parallel to and adjacent to the shaft.

2. A shaft in combination with a disc and a needle fastened to the disc, parallel and adjacent to the said shaft, a shank of said shaft being adapted to fit in a power rotated chuck.

3. A shaft in combination with a disc and a plurality of needles fastened to the said disc parallel to and adjacent to the said shaft, said shaft having a shank end extending through said disc, said shank end being adapted to fit in a power operated chuck.

In testimony whereof, I afiiX my signature.
